How Cold Weather Improves Solar Efficiency: Insights from Solar Mounting System Experts

Spain is leading the way in renewable energy, with over 50% of its energy now coming from solar and wind sources. Even in the colder months, solar power plays a crucial role in the country's energy mix.

At one point in February 2024, Spain's energy prices dropped to nearly €2 per megawatt-hour (MWh), compared to €67 per MWh in France—highlighting the year-round effectiveness of solar energy.

Colder climates, while often viewed as challenging for solar installations, can actually enhance efficiency.

Research shows that heat decreases solar panel efficiency, while cooler temperatures boost production.

This counterintuitive fact is particularly relevant for solar ground mounting systems, which are widely used in colder European regions.

Solar Mounting Systems and Cold Weather: A Surprising Efficiency Boost

There are quite a few areas in Europe with cold weather. But, cold temperatures aren't necessarily bad for solar power.

Unless there are extreme weather conditions with heavy snowfall, cold weather has a positive impact on solar installations, especially on a ground-mounted scale.

Here's how:

1. - Improved Efficiency in Cold Temperatures: Solar panels, such as those supported by HAINA Solar Tech’s solar ground mounting systems, perform better in cooler climates. The photovoltaic (PV) cells generate electricity from sunlight, not heat. In fact, PV modules tested at 25°C can lose 10-25% efficiency in higher temperatures. Cold weather keeps panels cooler, helping them produce more energy per sunlight hour.
2. - Snow Reflects Sunlight for Bifacial PV Modules: Snow has the added benefit of reflecting sunlight, which boosts energy output, particularly with bifacial PV modules. These panels can absorb light from both sides, making them ideal for regions with snow cover. Ground-mounted solar systems benefit greatly from this effect.
3. - Self-Cleaning Panels: Snow can act as a natural cleaner. HAINA Solar Tech’s expertly designed solar mounting systems are angled to allow snow to slide off easily, ensuring that panels are left clean and ready to capture maximum sunlight once the snow clears.

Solar Ground Mounting Systems: A Winter-Ready Solution

When it comes to choosing a solar mounting system, ground-mounted setups offer distinct advantages during winter. Here’s why solar ground mounting systems from HAINA Solar Tech are ideal for cold climates:

• - Optimal Angle for Snow Removal: Ground-mounted solar systems are set at angles that not only capture optimal sunlight but also allow snow to slide off effortlessly. This ensures minimal disruption to energy generation even after heavy snowfall.
• - Scalability and Accessibility: Ground-mounted systems also provide flexibility for future expansion. If your energy needs grow, HAINA Solar Tech’s solar ground mounting systems allow for easy scaling without the space limitations of rooftop systems.
